Well I had what I thought was a big temperature problem since my plant in the tent became very wilted and temps were around 90 degrees the other day, I think max hit about 94 or 96 in the tent near the canopy. I didn't think the wilting was due to lack of water since the soil was damp when I probed to the knuckle. It also didn't help that the a/c in the apartment had been off on a somewhat warm day. The AC had also been turned off in the apartment on the night in question, but I had been maxing out at around 86 degrees previously without AC and then with the AC I had been a few degrees cooler, maybe 82 max. I figured I should try to move the fans around like Tortured Soul had suggested. This was somewhat difficult as the reflector I have is a bit too big as it is for the tent. It would be no issue if the fan could be mounted outside the tent though. I would like both fans outside the tent, but I'm not sure where I can mount them.
Anyways, I now have it setup as this: duct runs from outside of tent with a 90 degree bend to block light, into the light, to the fan, out the tent, and out of the room; carbon filter above the light, taped directly to the fan, venting out the top of the tent, fan running maybe 1/8th of a turn above min speed; two 6" intake vents open at the bottom with 90 degree bent flexible ducting to block light. Sides of the tent are sucked in, but temperature seems to be slightly better. I am planning to get another fan, maybe a 4" and use it for a filtered intake and then run the tent exhaust out of the room as well. That should improve temps further. I mainly didn't run another exhaust out of the room from the tent yet since I wanted to see if this setup was even going to be better. With an intake fan, I can exhaust the tent at full speed without issue again and should be able to maintain temps very close to ambient temperature. I'm very hopeful that I'll be able to use the full power of the lamp. But I'm seeing what it will take to really run a 1000 watt light in a 4x4 tent. I think I read it takes an 8" fan to cool a 1000 watt bulb properly. maybe I can get an 8" fan, figure out how to mount it outside the tent, and hook that up to the light exhaust and use the two 6" fans for controlling the internal tent environment.
I decided to do a little experiment right now. I just turned off the tent exhaust fan with the temp sitting at 82.9 at the canopy. Time was 6:40. At 6:45, the temp is now hitting 85.3. At 7:10 the temp was at about 86.3 and the humidty had risen to 50%. I decided to turn the fan back on, but at full blast. In less than a minute, the temp is down to 83.5. I put the fan back on a nice low setting so it doesn't strain the tent too hard and it is holding at a nice 83.1. Ambient in the room is about 79 or 80. I suspect the next step I can take to reduce temps would be to vent the tent out of the room. Combine venting the tent out of the room with a full 440cfm flow through the tent and an 8" fan on the light, I think I can manage to run the full 1000 watts. If I can't pull the full 1000 watts, maybe I'll be able to at least run with the 600 watt setting through the hot part of the summer.
